This paper applies a new quality engineering tool based on Taguchi method to trajectory planning of non-cooperative approach for active debris removal, and evaluates the results of 1296 (L36) or 2500 (L50) cases by changing parameters, which comply with 7 inputs of products, 8 inputs of operations, and 10 outputs for evaluations. The results show the feasibility of applying this quality engineering tool and some suggestions to ADR trajectory planning.
